Successful fluid sealing of valves and pumps cannot be accomplished without the appropriate sealing device. Whether using mechanical seals or compression packing, one must understand the specific needs of the application.
While mechanical seals in general are considered the superior sealing device, they are more expensive and less versatile than compression packing. Compression packing is more versatile due to the vast selection of materials used to make it and the various ways it is constructed. Materials such as vegetable fibers, man-made fibers, metals, graphite, and hybrids are all used to make packing. Construction types include braided, twisted, wrapped (rolled, folded), extruded, laminated, bulk, and die formed.
Construction types of compression packing each have variations within. This article will focus on braided

Garlock compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment. The development of the compression packing line reflects the evolution and innovation in the materials used in its production. Garlock develops and manufactures it's own technical yarn braided into packing, along with high performance proprietary coatings, that are essential in this age of sealing performance requirements.
Garlock’s product line includes industry recognized Low Emission valve stem packing, leading-edge and award winning pump packing sets like dry-running DSA, and water saving HYDRA-JUST.
